Strategic Advice: When there is a lot of data presented in a table, be sure to focus only on the information that the question asks about (here, 1990 to 1999 and major hurricanes).
Getting to the Answer: According to the table, between 1990 and 1999 (which includes 1990-194 and 1995-1999), there were a total of 44+66=110 stoms. Of there, 5+20=25 were major hurricanes. Therefore, the portion you're looking for is `(25)/(110)` which is approximately 0.2273. (C) is the correct answer.
